Selena’s close friend Taylor Swift is reportedly responsible for the reunion after encouraging Selena to forget about her “trust issues” with Justin.

A source recently said: “When Selena hung out with Taylor she was really stressed out and frazzled about everything with Justin. But Taylor reminded her how crazy Justin is over her and to just try to stay above the fray.

“The problem between them stemmed from Justin texting other girls. So Selena is embarrassed by what he did because it makes her look stupid, that he would talk to these other girls, and she is also embarrassed that everyone is so invested in their relationship now because of his actions.” - Bang Showbiz
